Too Long; Didn't Read
In the front-end web development, people get glamorized by how everyone is talking about how they say: you don’t need any mathematics, there’s no complexity you just need some Html CSS & Javascript and you are ready for that up coming job. So you fail in that trap the trap of starting React or Vue, Angular without any prior or advanced knowledge in Javascript. To escape that trap, try to learn a book,course in Udemy, Pluralsight or maybe a free tutorial in Youtube about React.
